At 22.04 hours on 2 Sep 1940, U-46 attacked the convoy OB-206 about 200 miles west of Bloody Foreland and reported the sinking of a tanker and a freighter. However, only the Thornlea (Master John Robert Potts) was sunk in this attack. Three crew members were lost. The master and 18 crew members were picked up by HMCS Skeena (D 59) (LtCdr James C. Hibbard) and landed at Greenock. The chief officer and 13 crew members were picked up the next day by the Norwegian steam merchant Hild and landed at Sydney on 15 September.
